GLAND-ADJUSTER FOR STUFFlNG-BOXES.

I :JPECIFEOATION 'orming part of Letters Patent No. 326,522, dated September 15, 1885.

Application filed April 6, 1885.

To aZZ whom it may concern.-

Be it known that I, JAMES POWELL, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gland-Adjusters for Stuffing-Boxes, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide a device wherewith stuffingbox glands can be adjusted in the most convenient and expeditious manner, theimprovement being adapted to the piston rods of engines and pumps and the stems of valves, cocks, or other appliances that necessitate the use of stuffingboxes of any kind. In carrying this improve ment into practice I avail myself of the lead ing feature of the invention seen in Letters Patent No. 192,658, granted to me July 3,1877, but modify the device shown in said patent so as to allow a greater range of utility. I accordingly provide a head or cap of the engine or cook or other appliance with ayoke or pair of united standards having a prolongation or neck traversed by the piston-rod or valvestem or other member that plays within the stuffing-box, said neck being screw-threaded exteriorly for the engagement of a nut, the latter being preferably adapted to bear against an annular collar or ring that travels freely along said neck. Furthermore, this traveling collar has two or more push-pieces, stumps, pins, or other projections that bear against the outer end of the gland in order that said gland may be forced into the stuffing-box when the aforesaid nut is screwed against the collar, thereby compressing the packing to any desired extent, as hereinafter more fully de scribed.

In the annexed drawings, Figure l is a side elevation showing my improved gland-adj usting device applied to an ordinary globe valve or cock. Fig. 2 is an axial section of said device.

head, or nut, B, that carries a pair of standards, O O, the latter being united at top to form a neck or prolongation, D, whose internal thread, E, serves as a nut for the screw F surmounted with an ordinary hand-wheel or other convenient turning appliance, H. The neck D is screw-threaded exteriorly at I to reface of a ring or collar, K, whose central opening, L, is sufficiently large in diameter to enable said collar to travel along said neck without coming in contact with the threads I. Projecting rigidly from the under side of this traveling collar are push-pieces M M, adapted to traverse suitableguides,l l N, of the standards O O, the lower ends of said pins being inserted in pits or sockets O 0 near the opposite ends of the flange P of the gland B. This gland surrounds the piston-rod or valve stem G, and fits snugly within the stuffing-box S in the usual manner. To compress the packing in the aforesaid stuffing-box itis necessary only to turn the nut J around the screw I, so as to depress the collar K, which act causes the push-pieces M M to force the gland R down upon said packing with any desired pressure. To repack the stufiing-box said nut is turned so as to permit'the collar to be elevated and the gland to be lifted out of the cap B, thereby affording the most convenient access to said box.

From the above description it will be seen that the present invention is possessed of all the advantages incidental to the device seen in the patent previously alluded to, while at the same time the construction of the adjuster is simplified, the cost of manufacture reduced accordingly, and its range of utility greatly increased. It is to be distinctly understood, however, that the invention is not to be limited to globe valves or cocks, as it is evident the cap or head B that contains the stnffingbox S may either be applied to or constitute part of a pump, engine, steam-chest, or any other machine, device, or apparatus that necessitates the use of a gland to compress the packing in such boxes.

Furthermore, the traveling ring K is not to be considered an essential feature of the invention, as it is evident said collar may be dispensed with, as seen in Fig. 4, where the nut of the valve stexn or rod G, said stem being ceive a nut, J, that bears upon the upper sur- ICC J is represented as bearing directly upon the upper ends of push-pieces M M, the shape and size of which can be modified to suit any special engine or other apparatus to which the gland-adjuster may be applied; but in Fig. 6 said push-pieces are shown projecting from a ring, K, that is divided atk to form two separate sections.

I claim as my invention 1. The combination ofastem or rod,a pusher bearing against a gland surrounding said rod, and a nut that imparts the desired pressure to said pusher, which nut engages'with and travels along a neck that guides saidrod or stem, substantially as herein described.

2. The combination of a stem or rod, an adjustable collar having push -pieces bearing against a gland surrounding said rod, and a nut which imparts the desired pressure against the packing contained in the stufling-box within which said gland is fitted, said push-pieces being adapted to travel within suitable guides, N N, of the yoke or other device that carries said collar and nut, substantially as described.

3. The combination of a stem or rod, an adjustable collar having push-pieces bearing against a gland surrounding said rod, and a nut which imparts the desired pressure against the packing contained in the stufling-box within which said gland is fitted, said push-pieces being adapted to travel within suitable guides N N, of the yoke or other device that carries, said collar and nut, and having their unconnected ends seated in said gland, substantially as described. I

4. The combinaticn of stem or rod G, threaded neck D I, adjustable collar K L, push-pieces M M, guides N N, gland P R, and stufiingbox S, substantially as herein described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES POWELL.
